For example: Simpson 260 or equivalent. For test purposes, the air flow switch may be “wired out” of the system. This will eliminate the need for air flow across the sensing thermistor to energize the power supply (see Fig 23). NOTE: All tests to be performed with the Ozone Reduc tion Jumper intact. NOTE: When servicing the power pack components, all wiring must be routed to factory specifications. Power Supply Specifications The solid-state power supply is not designed for individual component

When odors are present, the addition of charcoal filters will neutralize odors, such as cooking odors, pet odors, cigar and cigarette odors, ozone, etc. Optional charcoal filters are available for your Air Cleaner. Refer to the parts list for the charcoal filter part number for your Air Cleaner. Charcoal filters require replacement. They cannot be washed. While there is no rule of thumb for how often they should be changed, you can use your best judgement based on the odors you perceive in your

With the 120 VAC power turned on at the circuit breaker for the furnace, push the air cleaner ON-OFF switch to the “ON” position (Figure 20). 2. With the furnace blower running, the air cleaner will be operating. An arcing or “snapping” sound may be heard. This will occur occasionally, however the unit is operating properly. 3. With the furnace blower running, the Operating Light should be ON. If the Operating Light is not ON this signifies that the cells need washing, or that trouble exists in

Blow on thermistor at air flow monitor. 120 VAC should appear at multimeter. Stop blowing and voltage should disappear in 10 - 15 seconds. 4. If voltage did not appear (Step 3), disconnect power to power pack. Locate air flow switch and remove power pack cover. Disconnect the three-pin plastic connector. Jumper the two female pins (white wire to white-brown wire) as shown in Fig. 23. Reconnect power to power pack. Turn power switch “ON.” A. If 120 VAC appears at multimeter, replace air flow moni

The control confirms these contacts are open at the beginning of each heat cycle. This would indicate a faulty pressure switch or miswiring. 3 RED FLASHES: This indicates the normally open pressure switch contact did not close after the inducer was energized. This could be caused by a number of problems: faulty inducer, blocked vent pipe, broken pressure switch hose or faulty pressure switch. 4 RED FLASHES: This indicates that a primary or auxiliary limit switch has opened its normally closed co
